Abstract: 1,072,231. Measuring temperature electrically. DEPENDABLE RELAY CO. Ltd. Nov.21, 1963 [Aug. 21, 1962; Nov. 1, 1962; Jan.24, 1963], Nos. 32089/62; 41459/62 and 3029/63. Heading G1N. A temperature measuring bridge has a thermistor 4 in one arm and resistors 2, 3 in a second arm, both arms being mounted in a probe unit A, and has resistors 5, 6 forming the other two arms mounted with a meter G in a measuring unit B, the units being connected together by plug means. The resistor 2 adjusts the calibration of the bridge, and the probe carries a further resistor 1 which adjusts sensitivity. The measuring unit B carries a D.C. supply and a Zener diode Z to stabilize the supply to the bridge, which is adjusted by a variable resistor P with reference to a standard probe held at a known temperature. A switch S applies the D.C. supply directly to the thermistor or to a further resistor to pre-heat the probe and so reduce the response time when a measurement is made. The probe A may be reverse plugged into the unit B to substitute resistors 9, 8 for resistors 2, 3 and thermistor 4, in order to monitor the battery level. The thermometer may be used in clinical applications with a range of 90‹F. to 106‹F. in 0À2‹ divisions, or the range may be extended (using resistor 1) down to 70‹F.

Patent GB-341147-A (GB)
IPC: C08B7/00
Filed: 1929-10-26
Abstract: Mixed esters are made by the simultaneous application to cellulosic materials of organic esterifying agents and nitrating agents of such strength that at least 3 per cent of nitrogen, calculated on the esterified product, is introduced; the proportion of nitrogen may exceed 10 per cent, and in one example is 13,79 per cent.  The organic component introduced may be a lower acidyl group such as acetyl, propionyl, or butyryl.  A suitable esterifying mixture contains nitric acid, preferably fuming, and acetic anhydride, optionally with a diluent such as glacial acetic acid.  Catalysts are not essential, but may be added, sulphuric and phosphoric acids being suitable.  When phosphoric acid is used, the acetic anhydride may be omitted. Temperatures below atmospheric, say 0-15 DEG  C., are preferred for the esterification.  The initial materials may be cotton cellulose, wood pulp, or the like, or cellulose derivatives containing free hydroxyl groups.  They may be pretreated with a lower fatty acid, such as formic, acetic, or propionic, in liquid or vapour form, with or without a catalyst.  In order to modify the solubility of the ester the mixture, after the reaction, may be mixed with sufficient water to hydrolyze any anhydride and then with additional water in the proportion of 15-100 per cent of the original cellulose and left to ripen.  After precipitation by more water, the product, especially when sulphuric acid has been used, may be further ripened by boiling with about 20 times its weight of water containing up to 0,05 per cent of sulphuric acid.  The mixed esters obtained are very stable, and may be used for explosives, lacquers, varnishes, films, laminated glass, &c.  According to the Specification as open to inspection under Sect. 91 (3) (a) wood pulp may be pretreated either as described in Specification 249,173, [Class 2 (ii), Cellulose &c.], or with an organic acid anhydride, with or without an organic acid. This subject-matter does not appear in the Specification as accepted.

Abstract: 900,716. Soldering. BRITISH UNITED SHOE MACHINERY CO. Ltd. Oct. 14, 1958 [Oct. 15, 1957], No. 32670/58. Class 83 (4). [Also in Group XVIII] A succession of can bodies 2 with side seams aligned is moved along a path past a yieldable solder applying member 20 having a solder discharging orifice 70 closely adjacent the seams. In an embodiment bodies 2 from a body-making device 3, Fig. 1, are fed along a stationary mandrel 4 by an endless chain 6 with the side seams 5 having inwardly formed overlapping portions (Fig. 6) facing downwards and fitting in a groove 13 in the mandrel. Flux is applied to the seams by a wick 14 in a container 16 and the bodies are brought to soldering temperature by an induction heater 18. Solder is then applied to the seams by a hollow curved resilient needle 20 mounted below the mandrel on an arm 22, Fig. 4, extending from the bottom of a solder reservoir 24 secured to a slide 26 adjustable vertically on a bracket 28, which bracket is adjustable horizontally on a frame 34. Solder as a solid bar B is fed into the top of the reservoir along a guideway 80 by an endless chain driven by a motor under the control of a mercury switch, one electrode of which is actuated by a magnet carried on one end of a lever 102 carrying on its other end a ceramic float 100 on the surface of the solder. The solder in the reservoir is melted by thermostatically-controlled heaters 40 and flows by gravity from the bottom of the reservoir, free of oxide and slag, to the needle 20 through passages 44, 46, 48 in the arm 22 also provided with a heater 50. The flow of solder to the needle is controlled by a needle valve 52 operated by a treadle. The needle of resilient tubular stainless steel is arcuate and is threaded into the arm 22 to communicate with the passage 48 and has a solder discharging portion 66 of eliptical section with an orifice 70 which is arranged to enter a re-entrant groove 68 of the seam. The orifice is formed on an axis X, Fig. 6, inclined to the vertical which bisects the re-entrant angle. The free end of the needle is attached to a wire 76 connected to one side of an electric heating supply, the other side of which is connected to the arm 22. The force with which the needle presses against the seam, which seam may be on the outside of the body or a straight lap joint, depends on the adjusted position of the reservoir.
